Review on role of lime on soil acidity and soil chemical properties

One of the chemical soil degradation difficulties which affect soil production in the Ethiopian highlands is due to soil acidity. These review efforts to put together soil acidity concept, causes extent and management practices. Soil acidity is the problem of agricultural activities in Ethiopian highlands or cultivated lands and is getting an increase. To adjust acid soils and increase yields of crops of their choices farmers need simple and supportable methods, such as liming. An important role for raising soil pH and enhancing crop productivity liming has play an important role. In Ethiopia, because of soil acidity and associated toxic nutrient availability the gap between probable and actual yield is very varied .The application of mineral fertilizers without adjustments  is simply wastage of resources, because acidic soils are not reactive those mineral fertilizer. Improving yield production and there by satisfying yield gains effective and efficient acid soil management practices is important .This review emphases on the role of liming on soil chemical properties and also causes and managements of soil acidity and its successive effect on soil fertility and crop yield, in addition to this Integrated acid soil management improves the permanence of yields and maximizes nutrient use efficiency
